In this paper, we propose a high-throughput pipeline architecture of the stream cipher ZUC which has been included in the security portfolio of 3GPP LTE-Advanced. In the literature, the schema with the highest throughput only implements the working stage of ZUC. The schemas which implement ZUC completely can only achieve a much lower throughput, since a self-feedback loop in the critical path significantly...
Mobile applications require the use of specialized design techniques to reduce power consumption and maximize battery life. New implementation technologies are able to reduce energy at the device level. At the same time, architectural choices can lead to significantly different power consumption profiles for equivalent implementations of the same function. In this paper we focus on the architectural...
Hardware support for floating-point (FP) arithmetic is an essential feature of modern microprocessor design. Although division and square root are relatively infrequent operations in traditional general-purpose applications, they are indispensable and becoming increasingly important in many modern applications. In this paper, a fused floating-point multiply/divide/square root unit based on Taylor-series...
In this paper, we propose a pipelined-architecture for high-throughput computation of multilevel lifting 2D discrete wavelet transform (DWT). The multilevel DWT computation is shared by the proposed devices based on pyramid algorithm (PA) and recursive pyramid algorithm (RPA), where the PA-based devices compute the lower order subands and the higher order subbands are computed by an RPA-based device...
